And chiming staves



CHARLES F. BEVERLY, OF SALEM, OHIO.

CROZING AND CHIMING STAVES.

Specification of Letters Patent No. 1,829, dated October 16, 1840.

To all whom it may concern:

Be it known that I, CHARLES F. BEVERLY, of Salem, in the county ofColumbiana and State of Ohio, have invented a new and useful machine tocroze, chime, cut, and edge staves by the means of knives fixed onvertical reciprocating gates from steamed or boiled or saturated timber;and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the annexed drawings of thesame, making part of this specification.

Figure l is a perspective view of the ma chine. Fig. 2 is a plan of thenotched iron plate; Fig. 3, one of the crozing and chiming knives; Fig.4, the other crozing and chiming knife; Fig. 5, the spring for keepingthe sliding platform against the gate.

Similar letters refer to similar parts in the figures.

Construct a firm and solid foundation A of timber framed together ofsufficient length and breadth; frame into this foundation four uprightposts B B B B two on each of the longitudinal sills of the foundationfar enough apart for the purpose required; into which are mortised andtenoned two parallel longitudinal rails C C and between which are placedtwo stout fiat boards D, E, parallel with the cross sills of thefoundation A; these tables are to be framed hori zontally and are to beof sufficient width toform tables of the requisite size. One edge of thetable D is'to come flush with the in side or face of the posts B, B,fronting the two remaining posts B B on the same sills and one edge ofthe other table E is to come flush with the outside of the posts B B.Then construct two vertical reciprocating gates G, g, of wood or metal,or both, and of suitable dimensions which are to run or slide in hooksor grooves or otherwise that are to be attached to or formed on the faceof the posts B B next the opposite posts B B and on the outside of theposts B B". On the face or front of the gate G near the top affix aknifeK for cutting the staves from the bolt or block, running across thegate with one end dropped from a horizontal line so as to cause theknife to pass through the timber obliquely. Said knife is to be set outfrom the face of the gate sufficiently to form the stave to the properthickness and is to be fastened with bolts or screws passing through theknife into or through the gate at each end and along the back or upperedge; parallel with the lower cutting edge of this knife cut a throat orpassage through the gate to let the staves pass out when out. Then maketwo knives F, F, for cutting the croze and chime at each end of thestave immediately before it is cut from the block and fix them securelyto the gate G below the knife K, one on each side.

Each knife is made of asingle piece of metal in the form of the requiredcrozeand chime and is secured by screws, bolts or other suitablefastenings at the ends which are extended in the form of flanges forthat purpose and the position of said knives is on a horizontal linedirectly below the knife K and at a suitable distance therefrom to admitcams or wedge shaped blocks between them which are designed, when thegate descends, to push back the table I, hereafter described, and as farapart as the required length between the croze of the stave. Each knifeis made of a plate of the best cast steel bent near one end to thefigure of the required croze as at a 66 Figs. 3 and 4, then obliquely asat Z) Z) to the shape of the required chime, then at right angles to thelastbend and opposite to the bend for the croze as at cc, then bent outon a direct line with the first end to form one of the flanges abovementioned as at (Z d, the said first mentioned end of the plate formingthe other flange as at e e. The lower edge is then brought to a finecutting edge.

The edge of the horizontal plate L (hereafter described) next the gateis formed to correspond with the shape of the knives F which are to movein the depressions f f and M M therein, while the straight edge of saidplate is brought near or against the face of the gates. There must bechannels or throats cut through the gate back of these knives for thechips to pass out. Upon and across the width of the table or plat-form Dclose to the inside of the posts B affix horizontal parallel side stripsH with grooves out along the inner edges for the sliding platform I toplay in; on the upper side of the stationary platform D flush with thefront edge thereof and at equal distances from the posts B fix a shortblock Z as thick as the part of the side strips H from the lower edge ofthe groove down to the bottom to keep the sliding platform I fromspringing or sagging in the center. On the front edge of the platform Ion the upper side place the plate of iron L before mentioncd. So as toprotect the edge of the timber when cutting; in the front edge of thisiron plate file or cut the depressions M f before mentioned for thecroze and chime knives to match in as the gate G moves up and down. Onthe under side of the sliding plat-form I near each end affix a shortblock 79 to extend from the front edge back past the back end of thestationary block Z on the center of platform D, which blocks p p onthesliding platform are rounded at the rear ends and serve as bearersfor the ends of a spring N thatruns lengthwise of and between theplatforms, being held to its place by two pins 41, n that pass upthrough the platform D near to and opposite of the back end of the blockl in the center of said platform. The sliding platform is held to theface or front of the gate with this spring N until the croze and chimeof the stave are cut when it is forced back (by the cams Q g on the gateG outside of the croze and chime knives and extending from them to knifeK in a perpendicular line) and thus protects the lower edge of thetimber while the knife is cutting the stave.

The timber to be cut is put on the sliding a platform I and as the gateGr passes down contracted at the same time and as soon as the knifeisagain raised the table is moved out again by the extension of saidspring.

On the face of the gate 9 near the top afiix a knife P for edging thestaves running straight or on a horizontal line across the gate back ofwhich cut a throat or passage for the chips to pass through. This knifeon the cutting edge should be made conveX- that is deepest in the middleand theedge should taper equally toward each endwhich trims the edge ofthe stave by an oblique or drawing blow of the knife from the centertoward each end. Said knife is to be fastened with bolts or screws ateach endand also on a parallel line near the back or upper edge in aslmilar manner to knife K and should be set out at the ends and come innearly flush with the front of the gate in the center of the knifelengthwise so as to trim the edge of the stave the most at each end thusform the bulge for the cask or barrel. On the stationary platform Ebetween the upright posts B B affix a platform Q raised at the edgefarthest from the gate 9 so as to form a bevel or inclined plane whichmakes the joint on the inside and outside of the edge of the stave. Onthe front edge of the platform on the upper side fasten a strip of ironwhich should correspond in shape with that of the knife and is to keepthe edge of the stave from crumbling or breaking-the stave should belaid fiat on the table with the crozed and chimed side up and whendressed on one side should be changed end for end in order to dresstheother side.

The gates G, g, are to take motion by means of pitmen S attached to ashaft T with a crank U on each end, and running parallel with the lengthof the machine through the center just above the sill or foundation thisshaft runs on bearings near each crank attached to cross braces V andmay take its motion by a belt or strap running over a drum or pulley onthe shaft. The different parts of the machine should be made tocorrespond with the size ofthe stave to be cut.

The block or bolt from which the staves are to be cut may be heldagainst the gate by a lever or otherwise by the hand of the operator orin any convenient mode and should be held firmly against the gate whilethe table I is receding from it.

. WVhat I claim as my invention and improvement is- The construction ofthe knives F F as before described for cutting the croze and chime incombination with thedepressions and bevels in the plate I correspondingwith the said knives F F, all as before described.
